JEWE LERS SOLDERING-CLAMP.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed April 22, 1908. Serial No. 428,691.

To all whom it may concern:

Be it known that l, TVVILLIAW C. (11.0w, a citizen of the United States,residing at Vancouver, in the county of Clark and State of frashington,have invented a new and useful Improvement in Jewelers Soldering-Clamps,of which the following is a specification, reference being had to theaccompanying draw ings.

My invention relates to that class of soldering clamps used by jewelersand others for holding light and frail articles in position forsoldering.

The object of my invention is to provide a device in which the verticalholding jaws may be adjusted horizontally with respect to each other,and which jaws are asbestos lined and pivoted at their centers to permitof a grip adjustable to the form and position of the object seized, andthe jaw holding arms may be separated and each used as a holder ofvarious tools. I attain these objects as well as other advantages by themechanism, construction, combination and arrangement of partsillustrated in the accompanying drawings, which form a part hereof.

Figure 1 is a front view of my device. Fig. 2 is a side view. Fig. 3 isa side view of part of single arm with holding tools inserted in thejaws. 4 is a sectional side view 01' one jaw with a small tool insertedin. its end. Fig. 5 is a sectional side view of one asbestos linedpivoted jaw.

Like letters and numerals refer to like parts throughout the views.

A and B are the vertical arms of the clamp. The said arms are composedof two members as 6-5 in Fig. 1. These members are lixedly secured toeach other at their lower ends and are of resilient material. Their freeupper ends are set apart a suitable distance. The member 6 iscontinuously vertical and is provided with a notch 7 through which thehorizontal part of the member 6 extends in sliding engagement. Themember 6 is bent at an angle in a convenient part thereof wherein a longnotch 7 is provided and extends horizontally through the notch 7 of themember 6, when it is again bent at an angle and extends upwardly to thesame height as the member 6. Each of the members 66 is provided with ajaw as for example 8-8. The jaws 8-8 are pivoted upon the pins 99 andare within boxes .10]() fixedly secured in a Vertical position to theupper ends of the members 6-6 of the clamp arms A-B. The jaws 8-8 haverecesses in their laces of suitable form and dimensions and theserecesses are iilled with asbestos or other substance 11 which is anon-conductor 01' heat. The members 6-45 are also each provided withvertical recesses 12-42 immediately behind the jaw holding boxes 1010each of which recesses is 01' a form adapting it to receive a tool suchas 13-13 or 14.1 l.

The arm .1 is provided with a split plug 15 of suitable length, havingits split end slightly expanded and is pivoted on the pivot 16 at thelower end of the arm. A, the opposite end of the plug being free. Thearm B is provided with a tube 17 fixedly secured to the lower end ofsaid arm at right angles to the same and of suitable 'l'ori'n anddimensions to receive the plug 15 therein a suitable distance. In Fig. 1a broken bar 18 is shown, a part of the same being held by the jaws ofeach arm. in 3 a ring 19 is shown within the grip of tools 1 l14 whichare placed within the receiving recesses 1212 of one of the arms.

it will now be seen that the operation of the clamp is as follows: Thearms i are adjusted a suitable distance apart to receive a spectacleframe or other article by sliding the plug 15 within the tube 17. Theobject to be soldered is then placed within the jaws of each aru alterthey are sprung apart and upon releasing them they hold the object asdesired. The non-(mnducting substance upon the lace of the jaws engagingthe object prevents the loss of heat when the solder is applied as wouldbe the case by a direct contact ol metal with metal. Should it bedesired to use one arm as a holder ol' auxiliary tools, the plug 15 isremoved iron. the tube 17 and may be bent downward to facilitategrasping and handling the arm 1'1. The two members 6-6 may then eitheror both be 'litted with auxiliary tools to be operated with each otheror singly. The arm B having the rigid tube 17 may be secured in a visefor instance with auxiliary tools in its upper end as in. the case ofthe arm A.

My device is peculiar to itself with respect to all others as it has theautomatically adjustable jaws and contains no set screws, thumb nuts orratchets as many others do and the asbestos lined jaws enable theoperator to work more satisfactorily and quicker when soldering anyobject.

Having thus fully described my invention, I claim:

1. A soldering clamp of the kind described, comprising an arm A,having'a jaw at its upper free end, and a split plug pivoted at one endto the lower end of the arm, also an arm B of similar construction tothe arm A, except in place of the split plug, it has a tube fixedlysecured at one end to the lower end of said arm B at right anglesthereto and of a fCiI'Dl adapting it to receive therein, said split pug.

2. A soldering clamp of the kind described, comprising an arm A having avertical resilient member free at the upper end and pivotally secured atits lower end to the end of a split plug, also provided with a pivotedjaw upon the upper end, said jaw being faced with a material not aconductor of heat, an arm B of similar construction to arr-n ii, exceptin place of the split plug, it a tube fixedly secured at one end to thelower end of said arm B at right angles thereto and 01' a form adaptingit to receive therein said split plug.
